The instrument cluster is attached to the front panel of the car with two nuts. The connections of the instrument cluster are made by printed wiring on a foil-coated getinax board. The board is fixed on the back side of the case. Wiring diagrams for instrument cluster (release before 1996 and after 1996) shown in fig. 7-39 and 7-40.

The speedometer has two counters of the distance traveled: one is total, and the second «daily». The readings of the second counter can be set to zero by the handle brought out through the glass of the instrument cluster. The readings of the daily counter can be reset only when the vehicle is stationary, by turning the knob clockwise.
Warning: In order not to damage the instrument cluster glass, do not clean it with any solvents.
